And in the area with low indoor population density, such as a corridor, the arrangement of the air outlet nozzles can be relatively sparse, and if the corridor area is only provided with two air outlet nozzles. That is, in the area with high indoor population density, the number of the air outlet nozzles should be larger than that in the area with low indoor population density.

Referring to fig. 3, based on the same concept, an embodiment of the present application further provides a fresh air processing method applied to the control device 300 in the foregoing embodiment. The method comprises the following steps: steps S101-S103.

Step S101: and receiving indoor air quality data detected by the detection device and air quality data inside the air outlet pipe.

The detection device is arranged indoors and in the air outlet pipe, and the control device firstly receives indoor air quality data and air quality data in the air outlet pipe detected by the detection device.

Optionally, the indoor air quality data includes indoor gas content such as carbon monoxide content, hydrogen sulfide content, and the like, and the indoor air quality data includes indoor gas content such as hydrogen sulfide content, formaldehyde concentration, and the like. Optionally, the air quality data also includes PM2.5 concentration and TVOC (Total Volatile organic compounds) concentration. If the detection device is also used for detecting the temperature and humidity data of the environment, the corresponding air quality data also comprises the temperature and humidity data of the air.

Step S102: and judging whether the indoor air quality data meet the preset standard or not and whether the air quality data inside the air outlet pipe meet the preset standard or not.

After receiving the indoor air quality data detected by the detection device and the air quality data inside the air outlet pipe, the control device judges whether the indoor air quality data meet the preset standard or not and whether the air quality data inside the air outlet pipe meet the preset standard or not, namely compares the indoor air quality data with the preset standard and compares the air quality data inside the air outlet pipe with the preset standard.

The control device compares the indoor formaldehyde content with the standard formaldehyde content and compares the formaldehyde content in the air outlet pipe with the standard formaldehyde content, and according to a comparison result, whether the indoor formaldehyde content meets the preset standard or not and whether the formaldehyde content in the air outlet pipe meets the preset standard or not are judged. In this embodiment, the manner of determining the formaldehyde content is only used as an example, and it should be noted that the manner of determining the other gas contents is the same as the manner of determining the formaldehyde content, and therefore, in order to avoid redundancy, the description is not repeated.

Of course, the predetermined criteria also include a standard level of particulate matter, organic matter in the air, such as a standard level of PM 2.5.

Of course, the preset standard also includes a standard value of the temperature and humidity of the air.

Step S103: and determining whether fresh air needs to be introduced or not according to the judgment result.

And finally, determining whether to introduce fresh air according to the judgment result. The following explains the three types of determination results.

Firstly, if the judgment result is that the indoor air quality data meets the preset standard, the fresh air is determined not to be required to be introduced.

When the judgment result shows that the indoor air quality data accords with the preset standard, the indoor air quality is good, fresh air does not need to be introduced from the outside, namely whether the outdoor air quality data is good or bad or whether the air quality data inside the air outlet pipe is good or bad, and the fresh air does not need to be introduced as long as the indoor air quality data accords with the preset standard.

Certainly, in the actual operation process, when the judgment result shows that the indoor air quality data meets the preset standard, the control device can control the first fan to be closed without introducing fresh air; the control device can also control the first fan to be continuously opened, so that the indoor good air state is continuously maintained. (it should be noted that, if the control device controls the first fan to be continuously turned on, the air quality data inside the air outlet pipe also meets the standard). Specifically, whether the control device controls the first fan to be closed or controls the first fan to be continuously opened can be set according to specific conditions, and therefore the control device is not limited in the application.

And secondly, if the judgment result is that the indoor air quality data do not accord with the preset standard and the air quality data in the air outlet pipe accord with the preset standard, determining that fresh air needs to be introduced.

It should be noted that the air quality data in the room does not meet the preset standard, and the content of one of the gases in the air quality data exceeds the standard content of the gas, or the content of a plurality of gases in the air quality data exceeds the corresponding standard content of the gas.

And when the judgment result shows that the indoor air quality number does not accord with the preset standard, the air quality data inside the air outlet pipe accord with the standard, the indoor air quality is poor, the air condition is poor, and the air quality data inside the air outlet pipe accord with the standard, the air quality inside the air outlet pipe is good. It is determined that fresh air needs to be introduced through the fresh air system.

In practice, the detecting device can detect the air quality data inside the air outlet pipe, but when the detecting device detects, the first fan is not necessarily in an open state, that is, the air inlet system is not in a working state, and then the air inside the air outlet pipe detected by the detecting device may be the air left inside the air outlet pipe before. At this time, before it is determined that the fresh air needs to be introduced, the method further includes: and determining that the first fan is in an opening state. That is to say before confirming to introduce the new trend, controlling means can judge at first whether first fan opens, has confirmed when first fan has opened when controlling means, then continues to open the fan, continues to introduce the new trend. If the control device judges that the first fan is not started, the control device firstly controls the first fan to be started, then receives whether the air quality data inside the air outlet pipe detected by the detection device meets the preset standard or not, and if the air quality inside the air outlet pipe still meets the preset standard, the fan is continuously started to continuously introduce fresh air. If the air quality inside the air outlet pipe does not meet the preset standard, a third result is obtained, and a third judgment result is described below.

It should be noted that, when the judgment result is that the indoor air quality data does not meet the preset standard, the control device can control the exhaust system to exhaust air, so as to exhaust indoor air to the outdoor, and the control device can also control the start of the alarm, so as to prompt indoor personnel.

And thirdly, if the judgment result is that the indoor air quality data do not accord with the preset standard, the air quality data in the air outlet pipe do not accord with the preset standard. And sequentially comparing the content of each item in the air quality data inside the air outlet pipe with the standard content of the corresponding gas and the content of the corresponding gas in the indoor air quality data according to a preset gas hazard level. And finally, determining whether fresh air needs to be introduced or not according to the comparison result.

It should be explained that the preset gas hazard level is divided into different levels according to the hazard degree of the gas, such as setting the hazard level of the toxic gas as a first level, the hazard level of the combustible gas as a second level, the hazard level of the polluted gas as a third level, and so on. And then comparing the gas content with the hazard grade of the first grade in the outlet air pipe with the standard content of the first grade gas and the first grade gas content in the room according to the grades. For example, the gas with the hazard grade of the first grade is carbon monoxide, and the gas content of the carbon monoxide inside the outlet pipe is compared with the standard content of the carbon monoxide and the gas content of the carbon monoxide inside the room. When the gas content of the carbon monoxide in the air outlet pipe meets the standard content of the carbon monoxide and the indoor carbon monoxide does not meet the standard content of the carbon monoxide, the fresh air is determined to be required to be introduced to reduce the indoor carbon monoxide content. When the content of the carbon monoxide in the air outlet pipe does not meet the standard content of the carbon monoxide, fresh air does not need to be introduced at the moment. If introduce indoor the aggravation that inevitably causes indoor air quality with the new trend that carbon monoxide does not accord with the standard, consequently when the inside carbon monoxide content of air-out pipe does not accord with the standard content of carbon monoxide, close first fan, stop the operation of air inlet system. If the carbon monoxide content of the air outlet pipe and the indoor carbon monoxide content both meet the standard carbon monoxide content, judging the content of the gas with the next hazard level according to the preset gas hazard level.

And if the carbon monoxide content of the air outlet pipe and the carbon monoxide content in the room both meet the standard carbon monoxide content, judging the content of the methane gas. And comparing the content of the methane gas in the air outlet pipe with the standard content of the methane gas and the content of the indoor methane gas. When the content of the methane gas in the air outlet pipe meets the standard content of hydrogen sulfide, and the indoor methane gas does not meet the standard content of hydrogen sulfide, fresh air is determined to be required to be introduced to reduce the content of the indoor methane gas. When the methane gas in the air outlet pipe does not meet the standard content of the artificial gas, fresh air does not need to be introduced. If introduce indoor the aggravation that inevitably causes indoor air quality with the new trend that methane gas content exceeds standard, consequently when the inside methane gas content of air-out pipe is not conform to methane gas's standard content, close first fan, stop the operation of air inlet system. If the methane gas content of the air outlet pipe and the indoor methane gas content both meet the standard methane gas content, judging the next gas according to the preset gas hazard level.

It should be explained that the purpose of setting the gas hazard rating in the embodiments of the present application is to more effectively control the air quality in the room. For example, if the indoor air quality data does not meet the preset standard, the second-level gas content exceeds the standard, and possibly, the air quality data inside the air outlet pipe does not meet the preset standard, and if the air outlet pipe is in the mode of the prior art, fresh air is not directly introduced. However, in the embodiment of the present application, the gas content in the air quality data inside the outlet duct may be sequentially compared with the standard gas content and the gas content in the indoor air quality data according to the preset gas hazard level. If the air quality data inside the air outlet pipe does not meet the preset standard and is that the gas content of the third grade exceeds the standard, fresh air can still be introduced, so that the gas content of the indoor second grade is reduced, and the harm degree of the gas of the second grade is larger. However, if the air quality data in the air outlet pipe does not meet the preset standard and the first-grade gas content exceeds the standard, fresh air cannot be introduced. If the fresh air with the first grade exceeding the gas content is introduced into the room, the further deterioration of the indoor air is inevitably caused, and the pollution degree of the indoor air is increased. Therefore, the preset gas hazard grade in the embodiment of the application is adopted to compare the gas content in the air quality data inside the air outlet pipe with the standard content of the gas and the gas content in the indoor air quality data, so that the indoor air quality can be reasonably and effectively controlled.

Similarly, also there is such a condition in the reality, and detection device though can detect the inside air quality data of air-out pipe, but when detection device detected, first fan was not necessarily in the open mode, and that is also the air inlet system was not in operating condition, and the inside air of air-out pipe that detection device detected then probably was the inside air of air-out of leaving over before. At this time, before sequentially comparing the gas content in the air quality data inside the air outlet pipe with the standard content of the gas and the gas content in the indoor air quality data according to the preset gas hazard level, the method further includes: and determining that the first fan is in an opening state. That is, before determining that fresh air needs to be introduced, the control device may first determine whether the first fan is turned on. If the control device judges that the first fan is not started, the control device firstly controls the first fan to be started, then receives whether the air quality data inside the air outlet pipe detected by the detection device meets the preset standard or not, and if the air quality inside the air outlet pipe still meets the preset standard, the fan is continuously started to continuously introduce fresh air. If the air quality inside the air outlet pipe does not meet the preset standard, comparing the gas content in the air quality data inside the air outlet pipe with the standard content of the gas and the gas content in the indoor air quality data in sequence according to the preset gas hazard level.

Referring to fig. 4, based on the same concept, a fresh air processing apparatus 20 is further provided in the embodiment of the present application. This new trend processing apparatus 20 includes: a receiving module 21, a judging module 22 and a first determining module 23.
